' CLOSURE FOR JARS, BOTTLES, AND OTHER BECEPTACLES.

To all whom it may concern:

Be it known that we, ALFRED INGRAM and HARRY INGRAM,l citizens of thev United States, and residents of Brooklyn, inthe county of Kingsand State of New York, have invented certain new and useful Improvements in Closures for Jars, Bottles,

and other Receptacles, of which the following is a specification.` Y

. The invention resides more particularly in a novel cap of tin or other suitable metal,

' with a special compressible gasket in the flange or skirt portion thereof, adapted to the effectual sealing of lass tumblers, jars and other containers. ne purpose of the invention is to provide l readily capable of being effectually sealed against plain exterior surfaces of a container, such as a glass tumbler, and another purpose of the invention is to construct such cap. andv gasket in such manner that when in sealing position they may be conveniently removed from the container. l

In carrying out our invention we provide a metal cap adapted to pass downwardly over the upper end of a container and having an encompassing ange or skirt portio-n which is specially shaped or grooved to receive a packing ring or gasket originally conforming to the shape of the groove, and

' the said groove and gasket are of such configuration that by pinching together in a vertical direction a projecting annulus'constituting a portion of the walls of the groove, the gasket may not only be compressed laterally against the exterior wall of the container but become exposed at its lower edges below the flange or skirt of the cap in convenient position to be engaged by a fork or other implement, by which the gasket maybe dislodged or withdrawn to a suflicient extent to permit the removal of the cap without undue exertion or danger of fracturing the container.

The invention will be fully understood Vfrom the detailed descriptionl hereinafter presented, reference being had to the ac'- companying drawings, in which:

`I nthe drawings, 10 designates a container, which may be aVV glass Y tumbler,

12 a downwardlydepending flange orskirt constitutinga portion of said` cap, 13 `an annular.: beading .or groove. formed inthe 11 the cap,

lower portion of said flange or skirt, and

V141 the gasket disposed within said groove and adapted toengage the. exterior wall of the container 10. t

The container 10 has plain exterior walls the cap 11V is adapted toclose the `upper end of the container and at the upper portion of its flange orfskirt 12 snugly encompass the upper outer portions of the conf tainer. The groove-portion 13 of the cap is of special formation in thatit has a downwardlyv and outwardly ldiverging wall v15, a wall 16 extending yinwardly and downwardly therefrom,y and alower flange or skirt portion 17 which extends downwardly from the lower edges of said wall 16, all

so I' 16meet at an angle, which we number 18.

The wall 15A inclines downwardlyV and outwardly from the upper portion of the flange or skirt 12, and hence starts ata point close to the exterior wall of the container 10. The

wall 16 is less in depth than'the wall 15, and hence the flange orjskirt 17 sets outwardly from the exterior surface of the container 10, leaving a substantial opening between its inner vertical face d the adjacent surface of the container.

The gasket 14 may be of any suitable compressible material, and it has an inner flat face 19 -to engage the e'xteriorsurface of the container and surfaces 20, 21, 22 fitting against the walls 15, 16, 17 of the cap, the

surface 2O diverging downwardly and outi wardly, the surface 21converging`downwardly and inwardly and the surface 22 be-L ing vertical anda ainst the inner Yvertical face of the flange 1 `The gasket 14.- is nor' mallyA supported within the lgroove 13,7 of

i The sealing operation may 'the adjacent portions of the the flangeor skirt 12 when said gasket and the walls of said groove are in their normal condition shown in Fig. 2, and hence thercap and 4gasket may be assembledy and thereafter appliedlupon the' container.

The method of sealing the gasket 1li against the container and therefore sealing the container itself is represented in Fig. l,

in which it may be seen that in the sealing operation the angular meeting portions of the walls 15, 16 of the flange 12 are pinched togetherv and in the pinchingV squeeze the gasket outwardly from the groove 13 and against the exterior wall of the container with a vforce causing the gasket yto very firmly bind against the container and not only seal the same but'effectually lock the cap upon the container. The pinching of walls 15, 16 together not only vforces'theY gasket material fromthe groove-13 and against the exterior of the container,.but results in the gasket being vertically elongated, reduced in diameter and exposed at its lower portion below the skirt or flange 12, the container thus `loe-- coming efliectua'lly sealed and the lower edge of the gasket being left .in an exposed -position where it' may be engaged by a fork or other tool and forced downwardly from-the cap at such time'as it may be desired to remove the cap from the container. r'he pinch'- ing togther of the adjacent portions of lthe walls 15, 16 also results in the flange being drawn upwardly, this also aiding inthe f' exposure of the lower edges of the gasket 14.

The gasket 14 is of considerable vertical depth, and hence may plain wall of the container throughout an adequate area and not only afford an effectual seal but securely retain the cap upon the retainer andprevent any accidental displacement of the cap therefrom. The squeezing of the adjacent portions of the walls 15, 16 together, as shown in Fig. 4L, also results in the exterior surfaces of thev gasket being securely bound against the inner wallslofthe grooved portion 13 of the flange or skirt 12. be performed by several simple mechanical expedients, one of which is illustrated in Fig. et', and involves the employment of dies 23 having a groove 24eadapted to be forced inwardly upon the angle section 13 of the cap and compel the adjacent portions of the walls 15, 16 to come together within the Vgroove 24, thereby compressing the gasket leagainst the container. lvVe will probably form the die in about three sections so as to encompass the cap and effect the moving together of the adjacent portions of the walls 15, 1.6 in one operation around the entire cap.

On reference to Fig. 4 it may be seen that all of the gasket material in the angular section 18 of the beading 13 of the cap villustrated in Fig. 3, Vhas been squeezed Voutjacentwalls 15, gether by the vdies 23, and hence Vthegasketless the 4members 25, 26, have,

engage the exterior wardly toward the container from lthe ad- 16, which are squeezed tois left ina position in whichitmayfbe dislodged downwardly from the cap, 1 and in yaddition those portions of the gasket which were held within the angular' section 18 of the beading 13 utilized in creating an effectual seal. ln'Fig. l what was the wall 16 of Fig. 3` is numbered 25 and the lower portion of the wall 15 of F ig. 3 and which becomes flattenedout in the sealing operation, we number 26 in'Fig. 4l, andthese parts 25,- 26 in the closure astransformed in the sealing operation Iconstitute an annular flange 27 ofdouble thickness. It may also be seen on reference to Fig. that the entire structure constituing y`the beading 13,

by thesealing operation, been moved inwardly `toward the containerv 10, thereby compressing the v gasket over an extended. area exterior surfaceof said container.

We call attention tothe factthat after the angular section `18 of the beading 13 is in its `final condition shown in Fig. 4;, the outer wall of the gasket, below the tapered surface20 thereof, is substantial-ly vertical, and

that thebeading 13, except forv itsl direct lateral pressure has substantially no infiu ence on the gasket., thus Jleaving the gasket against the vertically elongated in a downwardly direcV tion without being heldin any undercut or lateral cavity of the beading, all this being quite essential, because we desire to-secure an extended 4sealing Zone below the plain upper portion-ofthe flange 12 whichengages the outer walls of the container and also desire to provideL a lseal wherein the gasket may be removed by being "pulled `downwardly ing the same. In this case the inner wall of the gasket engages the plain wall of thereceptacle and thel outer wall ofthe gasket is against surfaces which do not require the tearing or mutilation of the lgasket in withdrawing the same therefrom, lthe `gasket being in no substantial undercut or lateral recess of the cap. In addition the sealing of the container vresults'i'n the gasket not only being compressed laterally, "but 4extended vertically in a downwardly direction and in being exposed below the cap so that Vit may be properly and conveniently removed with the useof a fork 4or other'convenient tool. le are quite well aware that it is not new to compressa gasket against the side of a container or below a'slioulder 'formed on the container, but we haveno knowledge that anyone preceding ourselves have produced a seal possessingthe characteristics of the invention sought to. be protected herein.

v What we claim as ourinventio'nfand desire to secure by Letters-Patent, is:

. Afrom the portion of the cap-engagl 1. A closure for a receptacle comprising a cap having an annular depending flange orV skirt portion to encompass the upper exterior walls of the receptacle, and a gasket within said ange or skirt portion, said skirt portion initially having a downwardly and outwardly diverging annular wall, a wall converging downwardly and inwardly from the outer edges of said first mentioned wall and a flange extending vdow wardly from the inner edge of said second wall, and said gasket being adapted on one face to engage the exterior wall of the receptacle and, initially, at its outer face said walls at their adjacent angular portions and lower flange, and said walls being adapted to be squeezed toward each other for forcing said gasket therefrom andagainst the plain exterior wall of the receptacle.

2. A closure for a receptacle comprising a cap having an annular depending skirt or flange to encompass the upper exterior walls of the receptacle1 and a gasket within said skirt portion, said skirt initially having below its upper portion a downwardly and f outwardly diverging annular wall, a wall converging downwardly and inwardly from the outer edges thereof and a flange extending downwardly from the inner edge of said second wall and set outwardly from the wall of the receptacle, and said gasket being adapted at its inner face to engage the exterior wall of the receptacle and at its outer face said walls and lower flange of said skirt, and the adjoining angular portions ofthe walls of said skirt portion being adapted to be squeezed together so as to force the gasket therefrom and against the exterior surface of said receptacle and expose a portion of the gasket below said lower flange, the gasket then being substantially free of any lateral recess in the flange of the cap and being capable of being pulled downwardly from its sealing position.

8. In combination with areceptacle having plain exterior surfaces, a closure of the character described therefor comprising a -cap having a depending skirt to encompass the exterior surfaces of said receptacle at the upper end thereof and formed with an upper plain portion and a lower beaded por-l tion, and a gasket held within said lower beaded portion, said beadedV portion initially comprising upper and lower walls and a depending flange set outwardly from the surface of said receptacle, said gasket at its inner face being adapted to engage the exterior surface of the receptacle and at its outer face said beaded portion of said skirt,

and said beaded portion of said skirt having adjacent annular portions squeezed together sition.

to force the gasket from said portionsand move said beading toward the container,

compressing the gasket againstv the container and exposing the lower edges of the gasket belowv said skirt, the gasket being thereby elongated vertically in a downwardly direction and being substantially free of any lateral recess in theflange of the cap tending to prevent the gasket from being pulled downwardly from its sealing p0- 4. In combination with a receptaclefhaving plain exterior walls, a closure of theV character described therefor comprising a cap having a depending flange or skirt portion adapted to encompass the exterior surfaces of the receptacle at theupper` end i thereof and formed with Yan upper plain section and a lower beaded section comprising upper and lower walls and a flange set outwardly-from said receptacle and extending downwardly from the inner edge of said lower wall, and a gasket in said beaded section, said beaded section being in the condition of having a portion of its said walls bent toward and against each other against' faces of the receptacle fat the upper end thereof and formed with an upper plain section and a lower beaded section comprising upper and lower walls of unequal length and a flange set outwardly from Said receptacle and extending downwardly from the inner edge of said lower wall, which is shorter than said upperwall, and a gasket in said beaded section, said beaded section being in the condition of having a portion of its said walls bent toward and against each other against the resistance of said flange or skirt porgasket and holding said gasket squeezed therefrom vertically elongated in a downwardly direction and compressed againsty the plain walls'of the receptacle.
